Recording key information and video at home helps your vet quickly assess the condition and arrange appropriate tests.
- Record the frequency, timing, and color of vomit
- Note bowel movement frequency, consistency, and presence of mucus or blood
- Weigh your pet regularly and track any weight changes
- Measure and record resting respiratory rate and any wheezing on multiple occasions
- Monitor for changes in alertness, activity level, and appetite
- Film breathing, walking, or elimination behavior and save for reference
- If symptoms persist or worsen, arrange a clinic visit with imaging capability as soon as possible
03How will the vet diagnose this? Common diagnostic tests
The vet will use imaging and lab tests to identify the underlying cause and refer for further evaluation if needed.
Chest and abdominal X-rays to assess gas distribution and organ size
Abdominal ultrasound to examine soft tissue and intestinal abnormalities
CT scan if needed to evaluate complex or deep-seated issues
Fecal examination, bacterial culture, or PCR testing to identify infectious causes
Blood tests to assess overall health and inflammatory response
Tissue biopsy or cytology to confirm suspected lesions
Referral to a specialist hospital if diagnostics exceed general clinic capabilities
04How to treat and care for your pet after diagnosis: medication, diet, and home care guide
Treatment mainly involves dietary adjustment and symptomatic management, with follow-up visits to monitor symptoms and test results.
- Switch temporarily to an easily digestible or low-flatulence prescription diet
- Administer medications as directed and schedule required follow-up appointments
- Continue to record gas, bowel movements, and appetite changes at home
- Return for regular check-ups to monitor weight and symptom trends
- Schedule follow-up imaging or fecal tests as needed to assess treatment efficacy
